How to Sign a PDF Online Free (Without Printing)
Add your signature to a PDF without printing or scanning. Draw or type your signature online for free — works on phone and desktop.
The Old Way vs the New Way
The traditional way to sign a document is painful: print it, sign with a pen, scan it back, and email it. That requires a printer, a scanner, and ten minutes you don't have.
The modern way takes 30 seconds and works entirely in your browser — no printer, no scanner, no app.
How to Sign a PDF on Breklo
1. Go to Breklo's PDF editor
2. Upload your PDF
3. Click the Signature tool
4. Either:
- Draw your signature with your mouse, trackpad, or finger (on touch devices)
- Type your name and choose a handwriting-style font
5. Place the signature where it belongs and resize it to fit
6. Click Download
The signature is saved as a transparent overlay, so it sits cleanly on the document without a white box around it.
Drawing vs Typing Your Signature
Drawing gives the most authentic look — it's your actual signature. On a phone or tablet, drawing with your finger works surprisingly well. The Breklo editor captures at high resolution so the signature stays crisp.
Typing is faster and more legible. Choose from handwriting fonts like Dancing Script or Great Vibes for a signature-like appearance. This is ideal when you need something quick and readable.
Is an Electronic Signature Legal?
In most countries — including the US (ESIGN Act), EU (eIDAS), and UK — electronic signatures are legally binding for the vast majority of documents. Contracts, agreements, and forms can all be signed electronically.
A few document types (wills, some property deeds) may still require a handwritten signature depending on your jurisdiction. When in doubt, check local requirements.
Signing on Your Phone
The Breklo editor works on mobile browsers. Open the PDF editor on your phone, upload the PDF from your files, draw your signature with your finger, and download. No app installation needed.
After Signing
Once signed, you might want to:
- Compress the PDF if it's large before emailing
- Merge it with other documents
- Add text fields or dates with the same PDF editor
